To: all. whom. 2'29 mag/ concern Beit known that 11,; ,GARL A-NINGER', 811gln8B1,;ai=C1t1Z11- of Germany, resid ng at Dusseldorf German- .have invented; certainnew and. useful: Improvements in Pivot- G uns', Particularly Adapted v for Submarines, for which. I have filed application in-Grer-v manyuJune 11918, and of which the follow ing, is a. specification.

The invention relates to an improrement for :rgunto be-used on: submarine; boats, which iSElQiE aconstruction as: simple as possible; in that part at least. which is awash while the 'boat'is submerged, Here such guns; are though of, which areaadapted to b'e pointed"front/inside; oi thesubmarine; in order to permit. of'thepointing, being done without; hindrance from the heavy seas; and. inorder. to liaveothe-gun: ready for fining immediatelyafter emerging; or that the, boat. may be ready"- at: onceto submerge" after:- firing; It. is no longer necessary forthe' crew to. come outon; deck, except for tfneloading mana Now it ise'most important. as regardsithe safety oi'i the-boat, thatthelattec is provided in its outer-shell WitliDfl'S 'i'ew perforations as possible, since these reqnirerspeci a1; tightening means; again.

This is attained. to :a. large extent by the present. invention in: that; only one: single packing is required for= movable parts namely that whicln is to tighten up the pivot'pin of thevgunz. AtJ-the; samev time saith-pivot pin Wllli serve as a. shaft for transmission of the movement oh: the 7 two pointing machines disposed in theahlold of the'boat, that is toa say,v 0t thetmachines tor vertical and horizontal pointing.

Theconstruction shoavs the-pturuthenadvantage-oi small resistance to -the= Water when submerged, and? besides the profile of the boat is not essentially enlargednbyothe guns.

The pointing of such gunsmayb'e eflected in the following manner:

Aided by a periscope, projecting pressuretightly from the boat (especially from the conning tower) the goal is made out. The movement of the prisms of the periscope is transmitted by manual means or by machinery to hands or pointers arranged inside the boat near the gun in such a manner, that the individual movement of the boat Serial, No. 481,060:

oil elevation; The marks-men now move the gun by means of the pointing machines manipulated either by hand or machinery, so that thehands or pointers driven by the gun will continuously tally with those pointersad-justed from the.- conning tower. Such-devices have: already becomeknownin pointers of back-sights.

In; the literature relatingflo gunnery furthermore devices have. become known, which will admit of the guns to be pointeddirectly iroma point of. sight in. any desired dis.- tance, that. is to say by dispensing with the intermediary, the marks-men above referred tOAA In the drawing onemodification according to; the invention is; illustrated; in which Fig; l is an elevation showing a longitudinal; section: throughthe boat andi the pivot alirangements,,-,

Fig. 2 is a: horizontal section through the hydraulic and compressed air; cylinders ;on

The barrel. and cradle are; i shown:- in full lines inyside elevation at an elevation of- O and in dottedvlines atan-elevation ol 4 50. 1 i

The cradle a rests withit-s trunnions-b in the; cradle: support-0;. whose.- hollow pivot member (Z carrying; a piston rests in the pedestal f, which: constructed asahydraulic cylinder, being provided atthetop with a packing-box g and: at the bottom with a packing-box in The pedestal is fastened to'the. pressure-safe body of they boat. The hollow journal cl is provided at its lower: endiiwith' a packing-box is, throughwhielra-- plunger Z is extending into: the pirotmember (Z adapted-to be; used! as a compressed air cylinder; Saidplungeris guided in'the: journal (Z-by means: 015 a groove and key. -w,. so that it is, free tos moire long-itudinally therein; its, turning however will cause the horizontal pointing movement of the gun. For this purpose, the plunger Z which rests by means of a ball-bearing me upon the bottom 71 of the boat, carries a toothed wheel 0, through which the horizontal pointing motion is imparted by the machine for horizontal pointing, not shown. Thehead of the pedestal f carries a ring 29 moving on balls, said ring being provided with two "ourna-ls Guidin rods 1" connect these journals with other journals disposed at both sides of the cradle;

If the cradle support 0 is raised or lowered byintroducing hydraulic pressure through the openings u or 01 onto the upper,

junction with the plunger Z said pivot member will constitute an 'equalizerqof,

compressed air.

The upper part of the compressed air cylinder is communicating \vith'its lower part through borings i Besides the aspects pointed out in the premises, the gun constructed according to the present invention ofliers the following advantages.

At a lesser elevation the height of firing is small and consequently I the recoiling power absorbed by the shell of the boat will be'small too. At an lncreasing'elevation the height of firing will increase but the horizontal component ofthe 'recoiling force be come smaller. The small elevatlon of the barrel when firinghorizontally allords easy loading of the gun. Intothis position the gun is preferably brought when the boat is to run submerged, so that the resistance of the water will be considerably lessthan with a gun of constant firing height.

Though hydraulic motion may be given the preference in the present instance, itwould not mean departing from the subject matter of the invention, by substituting elec trical motion, or to provide any other kind of motive power for raising or lowering the support of the cradle.

It is obvious, that the invention may be advantageously used with other guns than with those for submarines.

I claim:

1. In a pivot gun particularly adapted for submarines, the combination with the body of a vessel, of'a pivot member supported thereon and constructed to serve as a compressed air equalizer, a gun carried by the pivot member and means for raising and lowering the pivot member from within the vessel for adjusting the position of the gun.

2. In a pivot gun particularly adapted for submarines, the combination with the body of a vessel, of a pivot member supported thereon, a gun. carried by the pivot member, means for raising and lowerlng the pivot member from within the vessel for adjusting the position of the gun and means operable upon the raising and lowering of the pivotmember for changing the a ing a link pivoted at one end to the gun and transverse of the pivot member for swinging .ina planeparallel to the axis of said pivot member.

3. In a pivot gun, the combination with the body of a vessel, a pedestal supported thereon, a pivot member slidable in the pedestaha gun carriedby the pivot member, -means for raising and lowering the plvot member and rodspivotally connected at its opposite ends to the gun and pedestal for,

causing the angle of: the gun to be changed upon the raising and lowering of the pivot member. s s s s 4:. In a pivot'gun, a: pedestal formed with an axially arranged cylinder, a, hollow pivot member slidable in the pedestal and. pro vided with a piston operatingin the ,cyline der, a gun on the pivot member, and a plunger keyed in the hollow pivot member for relative sliding movement.

5. In a pivot gun, the combination with the body of a vessel, of a pedestal mounted thereon, a pivot member slidably mounted on the pedestal, a gun carried by the pivot member, rods swiveled to the pedestal and connected to the gun, and means for rotating and elevating the pivot member from within the inside of the vessel for the purpose of adjusting the elevation of the gun, said pivot member being hollow and constructed to serve as a compressed air equalizers 6. In a pivot gun the combination with the body of a vessel, a hollow pivot member supported thereon, a gun carried by the pivot member, a rotatable plunger extending into the pivot member and keyed thereto, said plunger when rotated causing the horizontal position of the gun to be changed, and means for raising and lowering the pivot member, said pivot member being adapted to serve as a compressed air equalizer.

In testimony whereof I have affixed my signature in presence of two witnesses.
